PC-50 Series Cylinder Port Single Pilot Operated Check Valve, 3/8 NPT Main Port, 1/4 NPT Pilot Port, Up To 8.00 GPM

Description & Features

Designed for industrial applications the Pilot Operated Check Valve provides reliable performance. This PC-50 series valve features a 3/8 NPT main port and a 1/4 NPT pilot port ensuring a flow rate of up to 8.00 GPM. Crafted with a robust cast iron body and a chrome alloy steel ball it includes a Delrin check seat and Buna-N O-rings making it highly durable under maximum operating pressure of 3000 PSI.

Its construction supports a variety of applications particularly where a control valve is in the neutral position thereby locking a cylinder without leakage. This valve allows flow to a cylinder and blocks reverse flow until pilot pressure is applied. It is vital for preventing movement of a load while the pressure source is inactive and requires a 4-way control valve to apply unlocking pressure.

With a pilot ratio of 4:1 the PC-50 Series Cylinder Port Single Pilot Operated Check Valve is crucial in lock valve circuits. Care should be taken to ensure the load is supported mechanically when servicing or removing the valve. Always refer to catalog recommendations for proper application.

how does the PC-50 series check valve work in a hydraulic system?

Answer by: Customer Support on Jul 20, 2025, 6:50 AM

The PC-50 Series Cylinder Port Single Pilot Operated Check Valve is used to control the flow of hydraulic fluid in a system. It allows fluid to flow in one direction while blocking flow in the reverse direction. The pilot port, which is 1/4 NPT, can be used to open the valve and allow reverse flow, making it useful for applications where controlled backflow is necessary. With a main port size of 3/8 NPT and a flow capacity of up to 8.00 GPM, it's suitable for various hydraulic systems that require reliable flow control.
